No. The skin's pH is around 5.5. It is slightly acidic to protect from the elements and from harmful bacteria growth.

Not everyone has the exact same pH. It varies from person to person.

You're confusing two different things - sebaceous and apocrine secretions are acidic but the stratum corneum (the outermost layer of your epidermis, which in contact with the environment) is neutral.

No, I'm not:

The pH of normal, healthy human skin is somewhere between 4.5 and 6. However, this varies with age. Typically, newborns have a pH closer to neutral (pH 7) that quickly turns acidic in order to protect young children’s skin.

Skin pH and the Acid Mantle

"Skin pH" is a chemist's term meaning "Potential of Hydrogen" and is used to measure the degree of acidity or alkalinity in the outer layers of the skin. It is measured on a scale ranging from 0 to 14 where the center of the scale, at 7, is neutrality (neither acid nor alkaline). A reading below 7 indicates that the substance being measured is acidic and above 7 is alkaline.

The acid mantle, the combination of sebum (oil) and perspiration, on the skin's surface protects the skin and renders the skin less vulnerable to damage. It also protects from attack by environmental factors such as the sun and wind and leaves it less prone to dehydration. Normal skin pH is somewhat acidic and in the range of 4.2. to 5.6. It varies from one part of the body to another and, in general, the pH of a man's skin is lower (more acidic) than a woman's. The acid mantle inhibits the growth of foreign bacteria and fungi causing the skin to remain healthier and have fewer blemishes. Acne, allergies and other skin problems become more severe when the skin become more alkaline.

Macworld claims that the ban even extends beyond screen protectors to include protectors and cushions designed to adhere to palm rest areas on Apple's notebook computers. Apple has yet to respond to either publication with comment on the reports.

That's fantastic timing...lol
